Strict Liability vs Absolute Liability: From Rylands v. Fletcher to the Oleum Gas Leak

Both strict and absolute liability impose liability without proof of fault. The difference is in the exceptions and the scope. Strict liability, created in England in Rylands v. Fletcher (1868), makes a person liable for the escape of a dangerous thing from his land, but allows several defences. Absolute liability, created by the Indian Supreme Court in M.C. Mehta v. Union of India (1987) after Bhopal and the Oleum gas leak, makes an enterprise engaged in a hazardous activity liable for any harm it causes, with no exceptions, and with damages measured by its capacity. It is one of India's most distinctive contributions to the law of torts.

1. Strict Liability: The Rule in Rylands v. Fletcher

The defendants' reservoir flooded the plaintiff's mine through old shafts, without negligence on their part; they were held liable. Lord Cairns added the requirement of non-natural use. The essentials are: (i) a dangerous thing brought or kept on land; (ii) non-natural use of the land; (iii) escape of the thing from the defendant's land to a place outside his control (Read v. J. Lyons & Co. [1947] AC 156, where an explosion inside a munitions factory injuring an inspector was not an 'escape'); and (iv) damage. The recognised exceptions are:

1. act of God (an extraordinary natural event, as in Nichols v. Marsland, 1876);
2. act of a stranger (a third party over whom the defendant has no control, as in Box v. Jubb, 1879);
3. plaintiff's own default;
4. consent of the plaintiff (express or implied, including common benefit); and
5. statutory authority.

In Cambridge Water Co. v. Eastern Counties Leather [1994] 2 AC 264, the House of Lords added that the type of damage must be foreseeable. Indian courts have applied strict liability, for example in M.P. Electricity Board v. Shail Kumar, (2002) 2 SCC 162, holding an electricity board liable for death caused by a snapped live wire, and in Kaushnuma Begum v. New India Assurance Co., (2001) 2 SCC 9, applying Rylands to motor accident claims.

2. Absolute Liability: The Oleum Gas Leak Rule

In M.C. Mehta v. Union of India (Oleum gas leak), (1987) 1 SCC 395, a Constitution Bench led by Chief Justice P.N. Bhagwati held that the Rylands rule, evolved in the nineteenth century, was inadequate for modern hazardous industries. An enterprise engaged in a hazardous or inherently dangerous industry that poses a potential threat to the health and safety of workers and residents owes an absolute and non-delegable duty to the community to ensure that no harm results. If harm results, it is absolutely liable to compensate all affected persons, and none of the exceptions to strict liability apply. The larger and more prosperous the enterprise, the greater the compensation, which must have a deterrent effect. The rule rests on enterprise liability (the enterprise that profits from the hazard must bear its cost) and the enterprise's superior capacity to discover and guard against hazards.

The rule was affirmed in Indian Council for Enviro-Legal Action v. Union of India (Bichhri), (1996) 3 SCC 212, which rejected the argument that it was mere obiter, and is reflected in Section 3 of the Public Liability Insurance Act, 1991 and Section 17(3) of the NGT Act, 2010.

4. Why India Needed Absolute Liability

Bhopal (1984) showed the inadequacy of Rylands: Union Carbide could have argued sabotage (act of a stranger) or that its victims were not 'outside' in the required sense, and the damages would not have reflected the corporation's wealth. The Oleum case was decided a year later, when the Court deliberately declined to be bound by English law, stating that it must evolve new principles to deal with unusual situations arising in a highly industrialised economy. The rule shifts the entire risk of hazardous activity to the enterprise, reflecting constitutional values under Article 21.
